Upon shut down I noticed a puddle of fuel on hanger floor. There is a small hole in belly of plane, almost directly under throttle area in cockpit, from where fuel is dripping. . I think the openings are for water collecting in plane. Two flights before this occurred I smelled fuel when shutting down but no leak at those times . Maybe the leak is from that area where throttle and other controls are located.. Should I open and expose that panel and take a look? Thanks for help...
